Weather conditions:

Weather conditions in summer were considered by local people to be slightly worse than usual; however there were no serious weather fluctuations that could have affected breeding birds.

BIOTIC CONDITIONS

Rodents abundance evaluation:

average

Breeding conditions:

Snowy Owls and Pomarine Skuas did not breed; several nests of Rough-legged Buzzard, Peregrine and Short-eared Owl were found, the latter being common. Small flocks of Long-tailed Skuas were recorded, but Arctic Foxes were not recorded at all. Waders bred successfully: numerous broods of Eastern Golden Plover, Red-necked Phalarope, Pectoral Sandpiper and Bar-tailed Godwit were recorded.
 

Rodent dynamics:

By 18-20 July, there were average numbers of lemmings, and pikas were numerous in the rocks, as were American Ground Squirrels and hares (especially near human settlements). One Narrow-skulled Vole was caught. Lemming index 8.8.
